Pyridylsulfonylureas as herbicides and plant growth regulators, processes for their preparation and their use

ABSTRACT

Compounds of formula (I), where R 1 , R 2 , n, W, R 3  and A are as defined in claim 1, are suitable for use as herbicides and plant growth regulators. They can be produced by a process similar to known processes. To produce them, new compounds of formula (II) are reacted with a carbamate of formula R*--O--CO--NR 3  A, where R 3  stands for phenyl or alkyl. The compounds of formula (II) can be obtained from the corresponding sulphochlorides.

It is known that some 2-pyridylsulfonylureas have herbicidal and plant growth-regulating properties; cf. EP-A-13,480, EP-A-272,855, EP-A-84,224, U.S. Pat. No. 4,421,550, EP-A-103,543 (U.S. Pat. No. 4,579,583), U.S. Pat. No. 4,487,626, 626, EP-A-125,864, WO 88/04297.

It has now been found that 2-pyridylsulfonylureas having specific radicals in the 3-position of the pyridyl radical are particularly highly suitable as herbicides and growth regulators.

The present invention further relates to processes for the preparation of the compounds of the formula (I) or their salts, which comprise

(a) reacting a compound of the formula (II) ##STR5## with a heterocyclic carbamate of the formula (III) ##STR6## in which R* is phenyl or (C₁ -C₄)alkyl, or (b) reacting a pyridylsulfonylcarbamate of the formula (IV) ##STR7## with an aminoheterocycle of the formula (V) ##STR8## or (c) reacting a sulfonyl isocyanate of the formula (VI) ##STR9## with an aminoheterocycle of the formula R³ --NH--A (V) or (d) first reacting an aminoheterocycle of the formula R³ --NH--A (V) in a one-pot reaction with phosgene in the presence of a base, such as, for example, triethylamine, and reacting the intermediate formed with a pyridinesulfonamide of the formula (II) (for example analogously to EP-A-232,067).

The reaction of the compounds of the formulae (II) and (III) is preferably carried out under base catalysis in an inert organic solvent, such as, for example, dichloromethane, acetonitrile, dioxane or THF at temperatures between 0° C. and the boiling point of the solvent. 1,8-Diazabicyclo[5.4.0]undec-7-ene (DBU) or trimethylaluminum or triethylaluminum is preferably used as the base.

The sulfonamides (II) are novel compounds. The invention also relates to them and their preparation. They are obtained starting from suitably substituted 2-halopyridines, which are reacted with S-nucleophiles such as, for example, benzylmercaptan or thiourea. The compounds formed in this way are converted with sodium hypochlorite or chlorine into the sulfochlorides (analogously to EP-A-272,855), which are then either reacted directly with ammonia or with tert.-butylamine via the tert.-butylamides with subsequent protective group removal to give the sulfonamides of the formula (II).

The carbamates of the formula (III) can be prepared by methods which are described in South African patent applications 82/5671 and 82/5045, or EP-A-70804 (U.S. Pat. No. 4,480,101) or RD 275056.

The reaction of the compounds (IV) with the aminoheterocycles (V) is preferably carried out in inert aprotic solvents such as, for example, dioxane, acetonitrile or tetrahydrofuran at temperatures between 0° C. and the boiling point of the solvent. The starting materials (V) required are known from the literature or can be prepared by processes which are known from the literature. The pyridylsulfonylcarbamates of the formula (IV) are obtained analogously to EP-A-44,808 or EP-A-237,292.

The pyridylsulfonylisocyanates of the formula (VI) can be prepared analogously to EP-A-184,385 and reacted with the aminoheterocycles (V).

The salts of the compounds of the formula (I) are preferably prepared in inert solvents such as, for example, water, methanol or acetone at temperatures of 0°-100° C. Suitable bases for the preparation of the salts according to the invention are, for example, alkali metal carbonates, such as potassium carbonate, alkali metal and alkaline earth metal hydroxides, ammonia or ethanolamine. HCl , HBr, H₂ SO₄ or HNO₃ are particularly suitable as acids for salt formation.

By "inert solvents" in the process variants above, solvents are in each case meant which are inert under the particular reaction conditions, but which do not have to be inert under all reaction conditions.

The compounds of the formula (I) according to the invention have an excellent herbicidal activity against a broad spectrum of economically important monocotyledon and dicotyledon weeds. Even perennial weeds, which are difficult to control and shoot from rhizomes, root stocks or other perennial organs, are well controlled by the active compounds. It is irrelevant here whether the substances are applied pre-sowing, pre-emergence or post-emergence. In particular, some representatives of the monocotyledon and dicotyledon weed flora which can be controlled by the compounds according to the invention may be mentioned by way of example without a restriction to certain species being intended by their mention.

On the monocotyledon weed species side, for example, Arena, Lolium, Alopecurus, Phalaris, Echinochloa, Digitaria, Setaria and Carperus species from the annual group and on the perennial species side Agropyron, Cynodon, Imperata and Sorghum and also perennial Cyperus species are well controlled.

In the case of dicotyledon weed species, the spectrum of action extends to species such as, for example, Galium, Viola, Veronica, Lamium, Stellaria, Amaranthus, Sinapis, Ipomoea, Matricaria, Abutilon and Sida on the annual side and Convolvulus, Cirsium, Rumex and Artemisia in the case of the perennial weeds.

Under the specific cultivation conditions, weeds occurring in rice, such as, for example, Sagittaria, Alisma, Eleocharis, Scirpus and Cyperus are also outstandingly controlled by the active compounds according to the invention.

If the compounds according to the invention are applied to the surface of the soil before germination, the emergence of the weed seedlings is either completely prevented or the weeds grow to the seed leaf stage, but then cease their growth and finally die completely after the passage of three to four weeks.

On application of the active compounds to the green parts of plants post-emergence, a drastic stop to growth also occurs very rapidly after the treatment and the weed plants remain at the growth stage present at the time of application or die completely after a certain time, so that in this manner weed competition which is damaging for the crop plants is eliminated very early and in a lasting manner.

Although the compounds according to the invention have an excellent herbicidal activity against monocotyledon and dicotyledon weeds, crop plants of economically important crops such as, for example, wheat, barley, rye, rice, corn, sugarbeet, cotton and soya are only damaged insubstantially or not at all. For these reasons, the present compounds are very highly suitable for selectively controlling undesired plant growth in agricultural productive plantings.

Moreover, the substances according to the invention show excellent growth regulatory properties in crop plants. They intervene in a regulating manner in the plant's own metabolism and can thus be employed for influencing plant contents in a controlled manner and for simplifying harvesting such as, for example, by causing desiccation and stunting of growth. In addition, they are also suitable for the general control and inhibition of undesired vegetative growth without killing the plants. In many monocotyledon and dicotyledon crops, inhibition of the vegetative growth plays a great role, as lodging can be reduced by this or completely prevented.

The compounds according to the invention can be used in the customary preparations in the form of wettable powders, emulsifiable concentrates, sprayable solutions, dusting agents or granules. The invention therefore also relates to herbicidal and plant growth-regulating agents which contain compounds of the formula (I) or their salts.

The compounds of the formula (I) can be formulated in various ways, depending on which biological and/or physicochemical parameters are given. Examples of suitable formulation possibilities are: wettable powders (WP), water-soluble powders (SP), water-soluble concentrates, emulsifiable concentrates (EC), emulsions (EW), such as oil-in-water and water-in-oil emulsions, sprayable solutions, suspension concentrates (SC), dispersions based on oil or water, oil-miscible solutions, capsule suspensions (CS), dusting agents (DP), seed dressings, granules for broadcasting and application to the soil, granules (GR) in the form of microgranules, sprayable granules, swellable granules and adsorption granules, water-dispersible granules (WG), water-soluble granules (SG), ULV formulations, microcapsules and waxes.

These individual formulation types are known in principle and are described, for example, in: Winnacker-Kochler, "Chemische Technologie", volume 7, C. Hauser Verlag Munich, 4th Edition 1986; Wade van Valkenburg, "Pesticide Formulations", Marcel Dekker N.Y., 1973; K. Martens, "Spray Drying Handbook", 3rd Ed. 1979, G. Goodwin Ltd. London.

The necessary formulation auxiliaries such as inert materials, surfactants, solvents and other additives are also known and are described, for example, in: Watkins, "Handbook of Insecticide Dust Diluents and Carriers", 2nd Ed., Darland Books, Caldwell N.J.; H.v. Olphen, "Introduction to Clay Colloid Chemistry"; 2nd Ed., J. Wiley and Sons, New York; C. Marsden, "Solvents Guide", 2nd Ed., Interscience, New York 1963; McCutcheon's "Detergents and Emulsifiers Annual", MC Publ. Corp., Ridgewood N.J.; Sisley and Wood, "Encyclopedia of Surface Active Agents", Chem. Publ. Co. Inc., New York 1964; Schonfeldt, "Grenzflachenaktive Athylenoxidaddukte" (Surface-active ethylene oxide adducts), Wiss. Verlagsgesell., Stuttgart 1976; Winnacker-Kuchler, "Chemische Technologie" (Chemical Technology), Vol. 7, C. Hauser Verlag Munich, 4th Edition, 1986.

Combinations with other pesticidally active substances, fertilizers and/or growth regulators can also be prepared based on these formulations, for example in the form of a finished formulation or as a tank mix.

Wettable powders are preparations which can be dispersed uniformly in water which apart from the active compound and in addition to a diluent or inert substance also contain wetting agents, for example polyoxyethylated alkylphenols, polyoxyethylated fatty alcohols and fatty amines, fatty alcohol polyglycol ether sulfates, alkane sulfonates or alkylbenzenesulfonates and dispersants, for example sodium ligninsulfonate, sodium 2,2'-dinaphthylmethane-6,6'-disulfonate, sodium dibutylnaphthalenesulfonate or alternatively sodium oleylmethyltaurate.

Emulsifiable concentrates are prepared by dissolving the active compound in an organic solvent, for example butanol, cyclohexanone, dimethylformamide, xylene or alternatively high-boiling aromatics or hydrocarbons with the addition of one or more emulsifiers. Examples of emulsifiers which can be used are: calcium alkylarylsulfonates such as Ca dodecylbenzenesulfonate or nonionic emulsifiers such as fatty acid polyglycol esters, alkylaryl polyglycol ethers, fatty alcohol polyglycol ethers, propylene oxide-ethylene oxide condensation products, alkyl polyethers, sorbitan fatty acid esters, polyoxyethylene sorbitan fatty acid esters, polyoxyethylene sorbitol esters.

Dusting agents are obtained by grinding the active compound with finely divided solid substances, for example talc, natural clays such as kaolin, bentonite and pyrophyllite, or diatomaceous earth.

Granules can be prepared either by spraying the active compound onto adsorptive, granulated inert material or by applying active compound concentrates by means of adhesives, for example polyvinyl alcohol, sodium polyacrylate or alternatively mineral oils, to the surface of carriers such as sand, kaolinires or granulated inert material. Suitable active compounds can also be granulated in the manner customary in the preparation of fertilizer granules, if desired mixed with fertilizer granules.

The agrochemical preparations as a rule contain 0.1 to 99 percent by weight, in particular 0.1 to 95% by weight, of active compound of the formula (I).

In wettable powders the active compound concentration is, for example, about 10 to 90% by weight, the remainder to 100% by weight is composed of customary formulation components. In emulsifiable concentrates, the active compound concentration can be about 1 to 85% by weight, usually 5 to 80% by weight. Pulverulent formulations contain about 1 to 25% by weight, usually 5 to 20% by weight of active compound, sprayable solutions about 0.2 to 20% by weight, usually 2 to 20% by weight of active compound. In the case of granules, the active compound content in some cases depends on whether the active compound is liquid or solid. As a rule, the content in the water-dispersible granules is between 10 and 90% by weight.

In addition, said active compound formulations optionally contain the adhesives, wetting agents, dispersants, emulsifiers, penerrants, solvents, fillers or carriers customary in each case.

For application, the formulations in commercially available form are optionally diluted in a customary manner, for example by means of water in the case of wettable powders, emulsifiable concentrates, dispersions and water-dispersible granules. Pulverulent preparations, granules for application to the soil or broadcasting and sprayable solutions are customarily not diluted further with other inert substances before application.

The required application rate of the compounds of the formula (I) varies, inter alia, with the external conditions such as temperature, humidity and the nature of the herbicide used. It can vary within wide limits, for example between 0.001 and 10.0 kg/ha or more of active substance, but it is preferably between 0.005 and 5 kg/ha.

Mixtures or mixed formulations with other active compounds, such as, for example, insecticides, acaricides, herbicides, safeners, fertilizers, growth regulators or fungicides are also optionally possible.

1. Weed action pre-emergence

Seeds or pieces of rhizome of monocotyledon and dicotyledon weed plants were planted in sandy loam soil in plastic pots and covered with earth. The compounds according to the invention formulated in the form of wettable powders or emulsion concentrates were then applied in various dosages to the surface of the covering earth as aqueous suspensions or emulsions using a water application rate of 600 to 800 1/ha after conversion.

After the treatment, the pots were placed in a greenhouse and kept under good growth conditions for the weeds. Visual assessment of the plants and the emergence damage was carried out in comparison to untreated controls after the emergence of the experiment plants after an experiment time of 3 to 4 weeks. As the assessment values show, the compounds according to the invention have a good herbicidal pre-emergence activity against a broad spectrum of weed grasses and weeds (cf. Table 5).

3. Crop plant tolerability

In further experiments in a greenhouse, seeds of a relatively large number of crop plants and weeds were planted in sandy loam soil and covered with earth.

Some of the pots were immediately treated as described under 1 and the others were placed in a greenhouse until the plants had developed two to three true leaves and then sprayed with the substances according to the invention in various dosages, as described under 2.

Four to five weeks after application and standing in a greenhouse, it was determined by means of optical assessment that the compounds according to the invention left dicotyl crops such as, for example, soya, cotton, rape, sugarbeet and potatoes undamaged pre- and post-emergence even at high active compound dosages. Moreover, some substances also spared gramineous crops such as, for example, barley, wheat, rye, sorghum millet, corn and rice. The compounds of the formula (I) thus have a high selectivity when used for controlling undesired plant growth in agricultural crops.
